LW37-35KV
The LW37-35KV is a high-performance outdoor three-phase AC SF6 circuit breaker designed for 35kV medium and high voltage power transmission and distribution systems. Manufactured in strict compliance with IEC 62271-100 and national GB standards, this professional high voltage switchgear is widely used in urban and rural power grids, industrial and mining enterprises, power substations, photovoltaic and wind power supporting power distribution projects for reliable circuit control and fault protection.
This 35kV SF6 circuit breaker adopts high-purity SF6 gas as the insulation and arc-extinguishing medium, equipped with advanced self-energy arc extinguishing structure. It features excellent dielectric insulation performance and fast arc extinction speed, with reliable short-circuit breaking capacity, which can effectively isolate overload and short-circuit faults in power grids. Compared with traditional vacuum circuit breakers, the LW37-35KV breaker has lower operating noise, smaller mechanical wear and more stable long-term operation performance.
Equipped with a mature and reliable spring operating mechanism, the LW37-35KV outdoor circuit breaker realizes accurate and consistent closing and opening actions with an extremely low failure rate. The overall fully sealed integrated structure undergoes professional anti-corrosion, waterproof, dust-proof and salt spray resistant treatment. It can adapt to various complex outdoor environments, including high altitude, low temperature, coastal humid areas and dusty industrial zones, achieving all-weather stable operation.
Featuring compact structure, reasonable layout and lightweight design, the LW37-35KV SF6 circuit breaker is convenient for on-site installation, hoisting and commissioning, greatly saving construction time and engineering cost. The equipment has extremely low daily maintenance requirements, effectively reducing the later operation and maintenance pressure of power grid projects and improving the overall operational efficiency of power systems.
With high safety, strong environmental adaptability and long service life, the LW37-35KV high voltage circuit breaker is mainstream core equipment for 35kV power grid construction and renovation. We provide global customers with factory direct sales, customized technical solutions, complete certification documents and professional after-sales service, delivering cost-effective power switchgear for various power engineering projects.
